ODEE is going to be, as it deserves to be, the standard etymological dictionary of the English language.
Times Literary Supplement
This is a very fine etymological dictionary, as aromatic a piece of lexicography as the great Onions (who, sadly died while the work was going through the press) ever achieved Anyone who wants to take journeys back through the mazes of the fickle human mind cannot very well do without this volume.
Anthony Burgess, Observer
